Cultivation method for hotbed chives

Abstract

The invention relates to a cultivation method for hotbed chives, belonging to the vegetable planting field. The cultivation method comprises the following processes of A, bedding and planting; B, managing water and fertilizers; C, cultivating hotbed chives, D, managing growth period and E, harvesting. Leek seedlings are planted in a leek plot; after a certain time of management of water and fertilizers, supports are arranged on the surface of the plot and a perforated black and white film is covered on the surface of the plot when the leeks grow to a certain height; the leeks are gradually excavated out from the holes; along the growth of the leeks, the length that the perforated black and white film covers the leek cauloid is increased through overstating supports, so the leek cauloid isconsistently in the condition without illumination and the cauloid is yellowed. When the leeks grow to a certain extent, green leaves at the upper part of the leeks are cut off; and then a common light tight black film is covered on the leeks; and the cut green leek leaves or straws are paved on the common light tight black film. The cultivation method for the hotbed chives provided in the invention saves heavy hilling labor; the leeks grow in the film holes, so the film has better supporting effect, the leeks have better permeability, and the disease resistance of the leeks is improved.

Description

technical field [0001] The invention relates to the field of vegetable planting, in particular to a method for cultivating chives. Background technique [0002] Chives are also known as "leek buds", "yellow leek buds" and "yellow leeks", commonly known as "leek white", which is the product of leeks that have been softened and cultivated to turn yellow. Chives are isolated from light and grow completely in the dark. Because there is no sunlight supply, they cannot produce photosynthesis and synthesize chlorophyll, which will turn yellow, which is called "chives". Chives are a high-end vegetable that the common people prefer. However, due to labor costs and production technology constraints, the production of chives is time-consuming and labor-intensive, which pushes up the price of this vegetable to a certain extent. But at the same time, how to reduce labor costs and improve unit output and quality is the best way to increase labor income. [0003] Traditional chive cultiv...

AI Technical Summary

Problems solved by technology

[0004] There are following disadvantages in the method of earth cultivation: 1, the labor intensity is big

Therefore, the labor intensity is very high

2. The unit planting area is small

Because the leeks used for the cultivation of chives need to be cultivated, the leeks are generally planted in the middle of the furrow with a distance of 40cm on both sides for soil cultivation, so the land utilization rate is not high

2. Highly affected by extreme weather

In summer, in the Zhejiang area, there are often severe rainstorms or typhoons. The leek ridges will be washed away by the rainstorm and the soil will be lost. The false stems of the leeks will be exposed, and the soil will need to be cultivated again, which will increase the amount of labor.

3. It is very difficult to prevent leek maggots

[0005] There are following disadvantages in the production of chives directly with black film: 1. The permeability between plants is poor, and it is easy to breed diseases and insect pests

Therefore, during the growth period, because the stems and leaves of leeks are long and scattered, the permeability is poor and they are easy to lodging, which is easy to breed diseases.

2. The quality of chives is poor

This method also utilizes common plastic film to cover planting chives, but when this method is used in the cultivation of Chinese chives, the above-mentioned problems will occur.
